I'm building a bluray, and I cannot figure out the polarity and set up: Would I connect just two wires to the &quot;battery side&quot; and have the diode arranged like this:
----------------------------
| Driver-------laser diode| Or two from the &quot;battery side&quot; and two to the &quot;diode side&quot; like this:
|+battery-----------Driver---------------+laserdiode|
| -battery-----------Driver-----------------laserdiode|
Sorry if this is hard to see, but please help. The reason this is urgent is that I'm going to my cabin in an hour, and will be building it there.
